Embodiment Construction

[0036]The present disclosure is directed to a pouch and a leak-proof or gastight closure mechanism therefor. While specific embodiments are discussed herein, it is understood that the present disclosure is to be considered only as an exemplification of the principles of the disclosure. Therefore, the present disclosure is not intended to limit the disclosure to the embodiments illustrated.

[0037]FIG. 1 illustrates a reclosable pouch 50 having a first sidewall 52 and a second sidewall 54 that are connected by, for example, folding, heat sealing, and / or an adhesive, along three peripheral edges 56, 58, 60 to define an interior space 62 between the first and second sidewalls 52, 54, an exterior space 64, and an opening 66 along a top edge 68 where the first and second sidewalls 52, 54 are not connected so as to allow access to the interior space 62 from the exterior space 64. A resealable closure mechanism 70 is disposed along the first and second sidewalls 52, 54 near the opening 66 an...

Abstract

A resealable vacuum-tight closure mechanism comprises a first closure element that includes a first base and a second closure element that includes a second base. A first contact surface on a first interlocking profile depends from the first base and a second contact surface on a second interlocking profile depends from the second base. The first and second contact surfaces provide a maximum occlusion distance when the first and second interlocking profiles are in an occluded state. A first sealing member extends from the first base, has a first length, is spacedly disposed from the first interlocking profile, and has a first sealing surface disposed thereon. A second sealing member extends from the second base, has a second length, is spacedly disposed from the second interlocking profile, and has a second sealing surface disposed thereon that is complementary to the first sealing surface. A sealing reservoir protrusion is disposed between the first sealing member and the first interlocking profile and has a volume sufficient to form a first gastight seal in a first occluded space between the first and second closure elements and bounded by the first and second occluded sealing members and the first and second occluded interlocking profiles upon formation of an end-stomp at an end of the first and second closure elements. A sum of the first and second lengths of the respective first and second sealing members is greater than or about equal to a length necessary to maintain a second gastight seal between the first and second sealing surfaces when the first and second interlocking profiles are in the occluded state.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]Not applicableREFERENCE REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT[0002]Not applicableSEQUENTIAL LISTING[0003]Not applicableFIELD OF THE INVENTION[0004]The present disclosure relates generally to a resealable closure mechanism, and more particularly to a gastight resealable closure mechanism such as may be used on a vacuum sealable container.BACKGROUND OF THE INVENTION[0005]Resealable closure mechanisms are commonly used on containers that may be used to store perishable contents, such as food. It may be advantageous for such a resealable closure mechanism to form a gastight seal when occluded, because a gastight seal allows the container to be evacuated and vacuum sealed. For example, after the container has been loaded with the perishable contents, a user may evacuate the container of excess gas, for example through an evacuation valve, and vacuum seal the container by occluding the gastight closure mechanism. Perishable cont...
